Topic: Windows 7 FireWire Performance problems

While the current RME FireWire drivers include full support for the new Microsoft FW driver included in Windows 7 there are still user reports that changing back to the 'old' legacy driver for the FireWire interface (the one in the computer) gives better performance. To change from the default driver to the older one:

Re: Windows 7 FireWire Performance problems

Hi all,

Thanks, Matthias, for this information.

I experienced a lot of ASIO drop-outs with the default ""Texas Instruments 1394 OHCI Compliant Host Controller" driver installed by Windows 7 64-bit for the FW controller on my Gigabyte motherboard. (I have a Fireface 400.) Changing to the legacy driver in the way you describe solved the problem.

However I note that with the same hardware under Windows 7 32-bit, the Texas Instruments driver worked fine with the Fireface.

I'm a bit concerned as to how long this "legacy" support is likely to be available, and whether using the older driver also has disadvantages. Needing to use the legacy driver in 64-bit Windows 7 feels like a step back. Is it a Microsoft problem, or something that can be fixed in an RME driver update? It's not quite clear to me why the problem would be happening with the driver written for the TI chipset (which is the chipset that everyone recommends for FW audio, too!).

This Post Fixed Everything. Thank you so much i looked long and hard a solution, even came across a forum post before this that said don't use legacy drivers because their for old versions of windows before 7. Not the case as i'm using windows 7 64bit and this has solved my audio problems with new Pro14.

Just installed w7-pro 64 with a new 1394 Card, PCI-Express DELOCK 2x ext. 1394A FireWire + 1x int, based on a Texas Instruments chip . The legacy driver did not solve my BSOD problem. I decided to try "Sunsway/ST Lab PCIe FireWire 2+1P" instead. It's based on a Via chip and that did the trick. I don't even need the legacy driver. I will keep the Delock Card for the future. Who knows? It might be this card that works in the future. The two cards are actually completely identical except for the chip

Re: Windows 7 FireWire Performance problems

Hello,

I´m running windows 8.1. I get the bluescreen "Driver Not Less Or Equal (Fireface.sys)". I can´t change to the legacy driver since it´s not in the list : "Let me pick from a list of device drivers on my computer".

So, how do I stop this from happening? Very annoying as you ofcourse understand....
